[lib] Deprecate updateRolesAndPermissions
Summary:
We want to deprecate this function because it's no longer relevant for *RawThreadInfos without member permissions.
We're keeping it around to ensure existing migrations work as expected.
Depends on D12598
Test Plan: This diff is just a rename to make it clear function shouldn't be used in future. Looked at all callsites and ensured there's nothing preventing function from being deprecated.
